Does mass affect the acceleration of an object in free fall
please give a sourceDoes mass affect the acceleration of an object in free fall?
if we are neglecting air friction, then mass has no effect on the rate of acceleration; all objects will accelerate near the surface of the earth at the rate of 9.81 m/s/s
the first answer is self-contradictory; aerodynamics will matter only if we consider the interaction between the moving object and air, and if we are considering those interactions, then the mass will certainly matter as well as the shape of the objectDoes mass affect the acceleration of an object in free fall?
Nope. Gravity and aerodynamics (the shape) will.
All objects (masses) fall (accelerate) to earth at the same rate, however, due to air resistence (friction) between the mass and the surrounding fluid (air) some will be slowed.
This is why a piano will hit the ground before a feather. The feather is aerodynamic (designed that way so birds can fly), and so there is higher pressure around it (just like an airplane wing), while the box-like piano is not aerodynamic and so it has lower pressure around it.
So, it is interesting to think that a 600 lb. piano will hit the ground before a 1000 lb. feather would. Yeah, that would be one big bird (hum, what is like a big bird and weighs a lot more than a piano? A plane!)

What object represents ';secrets'; in general to you?
i am doing a project, and for my centerpiece in this 3D art project, i have to use the theme secrets. i was thinking maybe i could make a 3D question mark, or something like that. but what are your ideas? what do secrets represent to you? any type of real-life object would be great, and multiple ideas would be awesome. Thanks!What object represents ';secrets'; in general to you?
A diary would be good because isn't that where most people keep their secrets.What object represents ';secrets'; in general to you?
a lock and key or a finger over lips in the ';Shhhh'; gesture
Pandora's box, or any type of box that is obviously locked.
A key.
A padlock.
A diary.
A closed door.
Good luck and God bless,

I would say to make Pandoras Box, since the whole story was about Pandora being curious about the secrets within the box.acne facial coconut oil

How do you plot a four dimensional object on a three dimensional grid?
plot it on a four dimentional grid and remove a dimentionHow do you plot a four dimensional object on a three dimensional grid?
Say for example you have drawn a cube on your grid paper, to plot the 4th dimension all you need to do is plot how the cube changes over a time scaleHow do you plot a four dimensional object on a three dimensional grid?
what is ur definition of the 4th dimension? is it time or inside/outside? Try:

is there such thing as 4d? only x,y and z are axes i know of
dont plot...
just explain...

What is the Definition of a real object?
Remember the chicken discussion in The Maxtrix. I liked that explanation.
What is reality? It is something we feel, smell, taste, see, or hear? But then again, all these sensations are electrical impulses that is relayed to our brain and our brain interpret those impulses. If that is true then something that is real is really our interpretation of impulses.
Let me ask, if a person with schizophrenia is hallucinating about a flower pot in front of him and everyone else around him doesn't see it. Does that mean its not real. It may not be real to everyone else but it is very really to that schizophrenic person.
Which brings me to my next point. I think reality is based on consensual and shared interpretations. If 100 people can agree that a red table is a red table then its a red table. well then again if you were color blind you wouldn't see red :). Now lets say another alien species which could see infrared saw that table. Our interpretation and the alien's interpretation of color would be very different. Lets take another example: a photograph. To most people a photograph can be easily identified. However, to a tribe in Borereo the photograph may represent a captured soul. In this instance culture definitely affects our interpretation of reality.
So to define what a real object is not very easy or even possible to do.
I also thought it was funny to describe the fourth dimension as time in defining an object. I mean what exactly does that mean. My table or photograph ain't got a clock on it last time i checkedWhat is the Definition of a real object?
Real objects are antithesis of imaginary objectsWhat is the Definition of a real object?
Go stand in front of a mirror.
You will see two of yourself.
The one you can touch is the real object.
its matter that u can feel...
Depends on your context. In optics, a real object is one that is physical and not an image.
I go back to Morpheus' explanation in the Matrix:
What is real? How do you define real? If it is something you can see, taste, or touch, then real is simply electrical signals interpreted by your brain.
You have to be careful with this question too, because it is awfully close to philosophy. Those quacks can spend hours on end arguing whether or not the chair in the middle of the room is actually there.
So, steering clear of philosophy, I would have to go with this: a real object is one that is under the influence of the laws of this Universe. In other words, it has to obey the laws.
The point(s) from which light rays diverge as they enter a lens or mirror.
any object that can be defined with for dimensions - three of space and one of time
A real object is one that doesn't go away just because you stop believing in it.
A real object is one that can be sensed with one or more senses or by their extensions.
The senses are touch, taste, smell, sight and hearing. Any instrument through which you can observe using one or more senses is an extension of the senses.
Any object or any existence that shows the characteristicness of limitation/limtless oriented dimentional application of height breadth width whose totality is nothing but the system of tangible/ non-tangible system as of massive substantiality as of mass or micro mass of matter or infinite system of space based on the basis of potential vacuity system having been involved in the same way as of described above[application] should be regarded as real object, beside this even space exist as real potentioal existence, because it exists as real existenc only unsubstantialy, %26amp; It should not be confused that it is non-existence entity because it exist as real, open [unlike closed systems as of mass or matter!!

If I have a heavy object and a light object and I drop it from the same height which would hit the ground 1st?
A heavy object and a light object are dropped from rest at the same time .If air resistance is negligible , the heavier object will reach the ground :
1)before the lighter one
2) at the same time as the ligher object
3) after the lighter object
4) at the same time as the lighter object but will experience greater acceleration
Hoping to get an answer as soos as possibleIf I have a heavy object and a light object and I drop it from the same height which would hit the ground 1st?
(2)
The mass of an object has no influence on the acceleration imparted on it by a uniform gravity field.
If the two objects are geometrically similar, they'd experience the same frictional drag on them during their fall.
In fact, on Apollo 15, a moon-walking astronaut dropped a hammer and a falcon feather from the same height at the same time. In the vacuum of space (no air on the moon) both hit the lunar dust at the same time. It was just a PR stunt, but it is a vivid illustration to the truth of the physics behind it.If I have a heavy object and a light object and I drop it from the same height which would hit the ground 1st?

Does anyone know the name of this object?
Somehow I cannot remember the name of this thing: It's a cylinder with mirrors %26amp; colorful beads inside, and when you peek through the hole the reflection of the beads create beautiful optical illusions.Does anyone know the name of this object?
